Answer 1

Answer: -3x + y = 3
3x + 2y = -12
-----------------add
3y = - 9
y = -9/3
y = -3

3x + 2y = -12
3x + 2(-3) = -12
3x - 6 = -12
3x = -12 + 6
3x = - 6
x = -6/3
x = -2

solution is (-2,-3)

The blue figure is a translation image of the black figure what write a rule to describe the translation

Answers

The translation rule from the blue figure to the black figure is -

$(x, y) \rightarrow (x - 4, \ y + 3)$

What are the types of translation of a graph?

There are three types of translations -

Reflection
Rotation
Dilation

Given is that the blue figure is a translation of the black image.

We can write the translation rule as -

$(x, y) \rightarrow (x - 4, \ y + 3)$

Hence, the translation rule from the blue figure to the black figure is -

$(x, y) \rightarrow (x - 4, \ y + 3)$

the answer is C. all you have to do is subtract the exponents

To divide variables, it is subtraction!

So, $a^3 - a^2 = a$

$b^2 - b = b$ . So in conclusion your answer is C. ab. Hope this helped!

How to find the inverse of the function f(x)=2x-3 ? Please

Answers

$f(x)=2x-3\n\ny=2x-3\n\n-2x=-y-3\ \ \ \ /:(-2)\n\nx=(1)/(2)y+(3)/(2)\n\nf^(-1)(x)=(1)/(2)x+(3)/(2)$

f(x)=2x-3
y=2x-3
x=(y+3)/2

f⁻¹(x) = (x+3) / 2

the distance between vancouver and winnipeg is 1850 km in a straight line. the distance on a map is 3.7 cm. write a scale statement for the map. what is the scale factor used to make the map?

Answers

Given:
1850 km
3.7 cm

1 km = 100,000 cm
1850 km * 100,000cm/1km = 1850 * 100,000 cm = 185,000,000 cm

scale statement: 3.7cm on the map represents 1850 km of actual distance between Vancouver and Winnipeg.

Scale factor used 3.7 cm : 185,000,000 cm or 1 : 50,000,000

185,000,000 cm ÷ 3.7 cm = 50,000,000

1.Four less than half a number is equal to 37 less than twice the number. a.Translate the sentence into an equation.

b.Solve the equation. Show your work.

Answers

Lets say the number is n

Four less than half a number is equal to 37 less than twice the number.
Four less than half n is equal to 37 less than twice n
Four less than $(1)/(2)$ n is = to 37 less than 2n
$(1)/(2)$ n - 4 = 2n - 37
